The chair is comfortable but the "leather" seating surface causes massive sweating after a few minutes. The manufacturer should find a way to insert but some fabric into the chair to minimize the discomfort of the unbreathable polyurethane material.
While once the chair was built it was incredibly comfortable the issue I experienced was actually on assembling the product itself. This product touts itself as being easy to install in less than an hour however I found this assembly more difficult as the pre-drilled holes that hold the back of the seat to the base were incorrectly drilled (crooked). When I tried to install the product both the arms bowed outward which made aligning the back of the chair incredibly difficult. I considered returning the product but when I checked stock it was sold out for 50+ miles from my home. Rather than dealing with the return/exchange process I uninstalled the arms from the base and connected them to the back of the chair first then fitting the arms over the base to secure them. It was then that I found that the pre-drilled holes on the right side were done at an angle which made the install incredibly difficult. 45 minutes later tired hands and several expletives later the chair is assembled.
It is so much bet5ter than my old chair. If you can read and follow dir4ections everything to put it together is in the box. However - the box will not fit inside a regular passenger car back seat because it really is BIG.
After setting up my chair I noticed that the height adjuster was not working at all. I have attempted everything and followed the instructions verbatim.
